Base Plate Thickness

Go Base Plate Thickness = 2*Maximum Cantilever Dimension*(sqrt(Bearing Pressure on Base Plate/Yield Strength of Base Plate))

Bearing Pressure on Base Plate

Go Bearing Pressure on Base Plate = ((Base Plate Thickness^2)*Yield Strength of Base Plate)/(2*Maximum Cantilever Dimension)^2

Yeild Strength of Base Plate

Go Yield Strength of Base Plate = (2*Maximum Cantilever Dimension)^2*Bearing Pressure on Base Plate/(Base Plate Thickness)^2

Equivalent Cantilever Dimension

Go Equivalent Cantilever Dimension = (1/4)*sqrt(Depth of Section of Column*Width of Flange)

Depth of Section of Column for Equivalent Cantilever Dimension

Go Depth of Section of Column = (Equivalent Cantilever Dimension^2)*16/(Width of Flange)

Width of Flange Column for Equivalent Cantilever Dimension

Go Width of Flange = (Equivalent Cantilever Dimension^2)*16/(Depth of Section of Column)

Allowable Bearing Pressure given Area of Lowest Column of Structure

Go Allowable Bearing Pressure = Columns Axial Load/Area of Foundation

Area of Foundation of Lowest Column of Structure

Go Area of Foundation = Columns Axial Load/Allowable Bearing Pressure

Load using Area of Lowest Column of Structure

Go Columns Axial Load = Allowable Bearing Pressure*Area of Foundation

Allowable Bearing Pressure when Full Area of Support is Occupied by Base Plate

Go Allowable Bearing Pressure = 0.35*28-Day Compressive Strength of Concrete

Allowable Bearing Pressure when Full Area of Support is Occupied by Base Plate Formula

Allowable Bearing Pressure = 0.35*28-Day Compressive Strength of Concrete
F_p = 0.35*f'_c

What is the significance of Base Plate in Foundation?

The eccentricity of loading or the presence of bending moment at the column base increases the pressure on some parts of the base plate and decreases it on other parts. To compute these effects, the base plate may be assumed completely rigid so that the pressure variation on the concrete is linear.

What is Allowable Bearing Pressure?

Allowable bearing pressure shall be considered to be the pressure at the base of a foundation in excess of the effective stress existing at the same level prior to construction operations. The allowable pressure depends on the strength of the concrete in the foundation and the relative sizes of a base plate and concrete support area.
